Here is the amstatus of our amdump.
What performance problems can be seen from the output below?
For ex.
12 dumpers busy : 0:02:30 ( 1.83%)
client-constrained: 0:02:30 ( 99.99%)
13 dumpers busy : 0:04:03 ( 2.95%)
client-constrained: 0:04:03 (100.00%)
14 dumpers busy : 0:00:06 ( 0.08%)
client-constrained: 0:00:06 (100.00%)
What improvements can be made to not have these
client-constrained messages?
